Having just recently become the site of a terrifying cliffside glass walkway, China's Zhangjiajie mountains are now also home to the world's highest and longest glass-bottomed bridge.
Connecting two mountain cliffs in the central Hunan province, the structure features 99 glass panels stretching across 430 meters (1,400 feet) suspended a spine-tingling 300 meters (984 feet) above the ground.
For safety reasons, only 8,000 people will be allowed to cross each day, and all of them have to reserve their tickets a day in advance for 138 yuan (US$20).
People wearing stilettos wlll be banned.
